Adjustable carrier for connecting a window pane to a motor vehicle window lift

ABSTRACT

An adjustable carrier for connecting a window pane to a window lift of a motor vehicle door, whereby the carrier is assigned to the motor vehicle door via guiding tracks. The carrier includes a base body and a holding body. The base body is guided on the guiding tracks of the window lift, and the window pane is clamped in the holding body. The holding body can horizontally sweep in relation to the base body, and a joint connection is provided between the base body and the holding body. An adjusting element which can be operated by a tool are provided for changing the position of the holding body provided for changing the position of the holding body relative to the base body. This position is directly or indirectly changed by an actuator in such a way that the position of the holding body relative to the base body remains unchanged when loosening or fastening the window pane.

The invention relates to an adjustable carrier for connecting a windowpane to a window lift of a motor vehicle.

The carrier is associated with the vehicle door through at least oneguide track and consists basically of a base body and a holding bodywherein the base body is guided on the guide track of the window liftand the window pane is clamped on the holding body. The holding body isable to swivel relative to the base body by means of a movabledisplacement means, and an articulated joint connection is providedbetween the base body and the holding body.

BACKGROUND OF THE INVENTION

From DE 44 35 008 A1 a solution is known for adjusting the window paneduring the course of assembly. The preferably frameless window pane isheld inside the door by guide tracks. The guide tracks are able toswivel in the transverse direction of the vehicle about a rotary axiswhich lies in the upper fixing point of the guide tracks. Adjustment ismade by an adjusting device at the bottom end of the guide track.

The drawback with this solution is that the space in the lower region ofthe door is restricted, as a condition of the distance between theturning point and site of the adjusting device so that no greatadjusting paths can be produced. Furthermore the entire installationarea is affected, that is the adjusting path has to be taken intoaccount when designing the whole door.

These drawbacks are overcome in DE-OS 28 43 634. The rotary axis of theswivel movement is here in the carrier. The carrier has a ball segmentwhich corresponds with a corresponding bearing shell. A tension screw ismounted centrally in the bearing shell and in the ball segment andengages into the hole in the pane to interact with a tension plate. Theadjustment and swivel movement is produced by swivelling the bearingshell. The position is fixed by tensioning with the tension screw.

Adjusting the window pane thus takes place freely within the area. Thatis, it is necessary to proceed stepwise by the trial and error method inorder to reach the correct position. If the ideal position is notreached with the current adjustment step then the pane clamp has to bereleased. Thus the previous position becomes lost and the nextadjustment step has to be introduced. As a condition of this settingprinciple an undesired vertical displacement takes place when adjustingthe pane across the driving direction.

With another solution known from DE 93 07 599 U1 the window pane isfixed on a separate part connected for articulated movement to the basebody of the carrier. Between this part and the carrier there is avertically displaceable wedge so that it is possible to change theangular position of this part relative to the carrier and thus theposition of the window pane relative to the vehicle body. The drawbackhere is that when the connection between the base body and holding bodyof the carrier becomes loose the connection between the holding body andwindow pane is also released at the same time.

From DE 35 45 856 C1 a carrier is known for a motor vehicle window liftwhich has a base plate guided between two guide rails and a holding railconnected to same through a ball joint for the purpose of holding awindow pane. Adjusting the position of the holding rail relative to thebase plate is carried out directly by means of a threaded bolt on thebase plate which engages in a threaded bush of the holding rail.

SUMMARY OF THE INVENTION

The object of the invention is to provide a simple solution forswivelling the window pane about an axis lying substantially parallel tothe driving direction and through which it becomes possible to positionthe window pane with precision against an associated sealing contour onthe vehicle body.

According to one variation of the solution, the base body and theholding body of the carrier are connected together by an articulatedjoint and adjusting means for changing the position of the holding bodyrelative to the base body are provided on the carrier and can beoperated by means of a tool from outside of the carrier and window lift(by an operator or robot for example). These adjusting means actindependently of the fastening means by which the window pane is fixedon the holding body of the carrier. The relative position of the holdingbody and base body can therefore be changed directly or indirectly byoperating the adjusting means so that even when the fixing of the windowpane is loosened later on this position remains set.

A displacement means in the form of a displaceable element (such as forexample a sliding wedge) is thereby associated with the adjusting meansand can be moved by the adjusting means in the direction of thearticulated connection between the holding body and base body so that anindirect connection is provided here. In order to form contact facesbetween the displaceable element with the base body and/or the holdingbody a circular arc shaped curved cylinder surface with the same radiusand same center point is provided both on the displaceable element andon the holding body or base body so that a complete surface contact isachieved during the course of displacement. This has the advantage ofmaking displacement simple and uncomplicated.

Displacement is carried out by operating the adjusting means fromoutside, preferably through the crash guard strip of the vehicle body.As adjusting means are adjusting screws, threaded spindles, threadedbolts or the like.

A turning angle on the adjusting means is assigned to a precisely fixeddisplacement path on the top edge of the window pane so that adjustmentcan take rapidly and with precision.

In another basic variation of the solution the displaceable partconsists of two segments of which each segment has a contact zone whichis connected to an associated contact area on the base body and/or onthe holding body and wherein the tangents at the contact faces, contactlines and/or contact points have different slopes. The position of theswivel axis of the window pane can thus be fixed through the variableslope of the tangents.

This solution has the advantage that the swivel movement of the windowpane is not bound to the structural design of the articulated joint butcan be fixed freely in space. The contact zones on the segments and thecontact areas on the base body and/or holding body can be designed sothat the window pane can be swivelled about any selected point in space.

DETAILED DESCRIPTION OF THE INVENTION

The following co-ordinate system will be used for indicating thedirections below:

x-axis: driving direction

y-axis: horizontal and transversely to the driving direction

z-axis: vertical and transversely to the driving direction

FIG. 1 shows the construction of a carrier. A base body 1.1 which isguided on a guide track (not shown here) of a window lift, is connectedfor articulated movement to a holding body 2.1.

The articulated connection is produced through a cylinder-shaped guidemember 30.1 which is associated with the base body 1.1 and whichcorresponds to a guide surface 31.1 formed on the holding body 2.1

In this area a full length through bore 32 is provided in the guidemember 30.1 and a corresponding threaded bore 20 is provided in theholding body 2.1 into which a clamping screw 120 engages.

The holding body 2.1 is associated with a window pane (not shown here).This window pane is supported on window pane holders 21.1 and isconnected to the holding body 2.1 through a window pane bolt (not shownhere) which is guided through the window pane bolt bore 22.1. A recess10.1 is provided in the base body 1.1 in order to ensure there issufficient space for the window pane bolt.

In the lower part of the carrier is an adjusting screw 50, the head ofwhich is embedded in a socket 23 mounted on the holding body 2.1 andengages in a threaded bore 11 of the base body 1.1.

In order to adjust the slope of the window pane the adjusting screw 50is turned and the distance between the base body 1.1 and holding body2.1 is changed in defined manner. The guide face 31.1 thereby slides onthe guide member 30.1 so that the holding body 2.1 is swivelled in they-direction relative to the base body 1.1. This movement takes placeabout a swivel axis 33.1 lying on the x-axis. The swivel axis 33.1 isnot fixed but shifts with the movement. The position of the window paneis also displaced slightly on the z-axis.

The clamping screw 120 serves to fix the position of the holding body2.1 relative to the base body 1 and thus to fix the slope of the windowpane.

FIG. 2 describes another design. Here the articulated connection betweenthe base body 1.2 and the holding body 2.2 is produced through an axis.designed as a clamping sleeve 34.1. Bearing tabs 35.1 are formed on theholding body 2.2 and engage in corresponding openings 13.1 in the basebody 1.2. Bearing bores 36.1 in the bearing tabs 35.1 hold the clampingsleeve 34.1 which is mounted in the bores 14 of the base body 1.2. Thusthe holding body 2.2 can swivel about the swivel axis 33.2 relative tothe base body 1.2.

Adjustment is carried out through a threaded bolt 51 which engages oneach side in steppe d bolts 52.1; 52.2. The stepped bolt 52.1 is mountedin the base body 1.2 and the stepped bolt 52.2 is mounted in the holdingbody 2.2, with these positions being fixed by plastics clips 53.1; 53.2.

The slope of the window pane is adjusted by the rotary movement of thethreaded bolt 51. One revolution results in a definite change in thesetting angle of the holding body 2.2 relative to the base body 1.2.

The position is fixed by a separate screw (not shown here). The windowpane is fixed in a similar way to the example explained with referenceto FIG. 1.

FIG. 3 shows a further embodiment of the invention. The holding body 2.3is here designed in three parts for the purpose of providing a smoothclamp around the window pane, and consists of a socket plate 24.1, aninsert 25.1 and a holding plate 26.1. The socket plate 24.1 is connectedto the base body 1.3 similar to the embodiment described with referenceto FIG. 2. The socket plate 24.1 is adjoined by the insert 25.1 whichsurrounds the window pane. The socket plate 24.1 supports a collar 27which engages in a hole in the window pane.

A fixing screw 28.1 provided for clamping the window pane engagesthrough the socket plate 24.1, through the insert 25.1 and through theholding plate 26.1 The fixing screw spreads out the collar 27 and thusfixes the position of the window pane. The articulated connectionbetween the base body 1.3 and the holding body 2.3 is produced similarto the example described with reference to FIG. 2.

A threaded bore 28.2 is formed in the holding plate 26.1 to hold thefixing screw 28.1 which engages into the threaded bore. By turning thefixing screw 28.1 the holding plate 26.1 is drawn against the socketplate 24.1 and thus the window pane becomes clamped.

Adjusting the slope of the window pane is carried out through anadjusting screw 54.1. One side of the adjusting screw 54.1 engages in athreaded bore 15 which is formed on a projection 16 of the base plate1.3. The adjusting screw 54.1 has a collar 54.2 which bears against aprojection 29 of the socket plate 24.1 through a rubber buffer 55 and inthe installed position projects into the area of the holding plate 28.2.By turning the adjusting screw 54.1 the collar 54.2 presses against theprojection 29 so that the adjustment process can be produced in thisway.

FIG. 4 shows a further design of the invention. The window pane 7 isclamped as in the embodiment according to FIG. 3 through an insert 25.2between a socket plate 24.2 and a holding plate 26.2. The socket plate24.2 is connected for articulated movement with the base body 1.4through a bolt 34.3.

A threaded member 56 is mounted centrally in the base body 1.4 in athreaded bore 17. A threaded spindle 57 runs through the threaded member56 and through a bore in the holding body 2.4. The ends of the threadedspindle 57 are assigned nuts 58.1, 58.2 wherein the nut 58.2 has aleft-hand thread and the nut 58.1 has a right-hand thread. The threadedspindle 57 has in the region of the threaded member 56 a square edge57.1 which engages in a correspondingly shaped contour of the threadedmember 56.

Adjusting the window pane 7 proceeds as follows:

One of the nuts 58.1, 58.2 is loosened. Then the spindle 57 is turned.The opposing nuts 58.1, 58.2 are thereby entrained. The rotary movementof the spindle 57 is determined by the square edge 57.1 on the threadedmember 56. This stands in engagement with the base body 1.4 through athread. As a result of the rotation of the spindle 57, the threadedmember 56 is moved on the y-axis relative to the base body 1.4 and ispressed against the holding body 2.4 so that this is swivelled about thebolt 34.3.

After the adjustment process the position is fixed by tensioning thenuts 58.1 or 58.2.

A further embodiment is shown in FIG. 5. The articulated connectionbetween the holding body 2.5 and the base body 1.5 correspondssubstantially to the embodiment as described with reference to FIG. 1.

The displacement of the holding body 2.5 relative to the base 20 body1.5 is carried out by a displaceable part, which is designed here as asliding wedge 4.1. The sliding wedge 4.1 is mounted between the holdingbody 2.5 and the base body 1.5. The contact surface 18 associated withthe base body 1.5 and the contact surface 40 associated with the slidingwedge 4.1 have ribs to enable a gripped contact between the base body1.5 and the sliding wedge 4.1.

Changing the position of the holding body 2.5 relative to the base body1.5 is carried out by moving the sliding wedge 4.1 on the z-axis.

With the design illustrated in FIG. 5 a spline 41 is attached at theside of the sliding wedge 4.1 into which a pinion 511 engages as a partof an adjusting tool 510. The adjusting tool 510 is mounted in a bore ofa tab 19 formed on the base body 1.5.

By turning the adjusting tool 510 the sliding wedge 4.1 can be moved onthe z-axis and thus the slope of the holding body 2.5 relative to thebase body 1.5 can be changed.

Fixing this position and fixing the window pane are carried out througha fixing screw 28.3 which engages through recesses (visible in FIG. 5but not numbered) in the base body 1.5, in the sliding wedge 4.1, in theholding body 2.5 and in the window pane (not shown). This fixing screw28.3 is assigned a nut (likewise not shown) so that the window pane canbe clamped in the desired position.

The example illustrated in FIG. 6 corresponds in its designsubstantially to the example illustrated in FIG. 5. The displacement ofthe sliding wedge 4.2 is here achieved through an adjusting bolt 43mounted centrally in the holding body 2.6 in a bore 42. This adjustingbolt 43 has a spline 43.1 which is connected to an internal spline 44.2attached on one side in a recess 44.1 of the sliding wedge 4.2. Byturning the adjusting bolt 43 it is possible to move the sliding wedge4.2 in the z-direction and thus to produce the desired position.

A fixing screw 28.4 engages in a threaded bore 43.2 of the adjustingbolt. The window pane can thus be tensioned in the desired position.

In an advantageous design of the contact surfaces between the slidingwedge 4.2 and the base body 1.6, they are formed as circular arc shapedcurved surfaces. The radii R, R′ of the circular arc shaped curvedsurfaces are approximately the same size and have a common center point(not shown here). This allows a contact bearing over the entire surfacewhatever the position of the sliding wedge 4.2 relative to the holdingbody 2.6.

FIGS. 7 and 8 show a solution where the displacement is likewise carriedout through a sliding wedge 4.3.

The holding body 2.7 corresponds in its construction substantially tothe example described with reference to FIG. 3. The window pane (notshown here) is held in an insert 25.3 and is clamped through the socketplate 24.3 and the holding plate 26.3. The holding body 2.7 is bound tothe base body 1.7 through fingers 35.3 which are mounted in the upperpart of the socket plate 24.3 and engage in corresponding recesses 13.2in the base body 1.7.

The sliding wedge 4.3 whose contact surfaces with the base body areformed as in the previous example as circular arc shaped curvedsurfaces, is mounted between the base body 1.7 and the socket plate24.3. A recess 44.3 is mounted centrally in the sliding wedge 4.3 and aneccentric 513 is mounted in the recess. The engagement in the eccentric513 is formed as an internal hexagon 514 in which engages a bush 515having a hexagonal outer contour.

This bush 515 is mounted with its hexagonal outer contour in positiveengagement in an internal hexagon 451 of the adjustment bush 45. Thisinternal hexagon 451 continues as a threaded bore 453 wherein theadjustment bush 45 is provided in this region with an external hexagon452. A clamping screw 12 with screw head 12.4 is mounted inside the bush515 and has a collar 12.3 which adjoins the base body 1.7. The other endof the clamping screw is provided with an external engagement 12.1 whichis formed for example as a torus or external hexagon. The shaft of theclamping screw 12 supports a thread 12.2 which engages with the thread453 of the adjustment bush 45.

In order to change the slope of the holding body 2.7 and thus the slopeof the window it is necessary to proceed as follows:

The external hexagon 452 of the adjustment bush 45 is seized and turnedby a suitable tool. The rotary movement is transferred through theinternal hexagon 451 of the adjustment bush 45 to the bush 515 and thusto the eccentric 513. This moves the sliding wedge 4.3 on the z-axis sothat the position of the holding body 2.7 relative to the base body 1.7is changed.

If this ideal position is reached then this position is fixed by seizingthe clamping screw 12 round its external engagement 12.1 with a suitabletool and tensioning it relative to the adjustment bush 45. The externalhexagon 452 of the adjustment bush 45 is thereby held.

In FIG. 17 a solution is shown wherein a sliding wedge 4.6 is mountedbetween the base body 1.6′ and the holding body 2.6′. This sliding wedgeis arranged so that its taper points in the x-direction.

As the sliding wedge 4.6 moves in the x-direction (direction of arrow),the contact surfaces 40.1; 40.2 of the sliding wedge slide on theassociated contact surfaces 181 on the base body 1.6′ or on the contactsurface 231 on the holding body 2.6′.

This results in the holding body 2.6′ swivelling relative to the basebody 1.6′ about the articulated connection which can be seen in FIG. 17but is not marked in any further detail.

In order to ensure the contact surfaces 181, 231 bear against each otherover their entire surface area they are provided with a restrictionwhich is not shown in the drawings.

The movement of the sliding wedge 4.6 is carried out by adjusting meansas already described in the above examples.

A further variation of the solution is described in FIG. 9 in connectionwith FIG. 10. Here the window pane 7 is held between a holding plate26.4 and a displaceable part 4.4 wherein an insert 25.4 is providedbetween the holding plate 26.4 and the window pane 7. This unit istensioned with the base body 1.8. The tensioning is produced through afixing screw 28.5 which is screwed into the holding plate 26.4 and whichruns through corresponding recesses (not shown in further detail in thedrawings) to fix the window pane 7.

The displaceable part 4.4 consists of two segments 4.4′, 4.4″ which arefixedly connected together. The segments 4.4′, 4.4″ have contact zones46.1′; 46.1″ which are in connection with contact areas 47.1′, 47.1″ ofthe base body 1.8.

In order to ensure the contact zones 46.1′, 46.1″ bear with their entiresurface area against the contact regions 47.1′, 47.1″ duringdisplacement, here both the contact zones 46.1′, 46.1″ and the contactregions 47.1′, 47.1″ associated with same are designed as circular arcshaped curved surface areas. The radius Rl of the upper segment 4.4′ islarger than the radius R2 of the lower segment 4.4″ Both have a commoncenter point M (see FIG. 10).

In order to change the position of the window pane 7 the displaceablepart 4.4 is moved on the z-axis. The socket body 2.8 thereby moves withthe window pane 7 about the center point M.

The center point M does not move during the adjustment process. The spotA marked in FIG. 10 is the spot where the perpendicular from the centerpoint M to the surface of the window pane 7 includes a right angle withthe tangent at this place. This spot A has as a result of displacementalso a component of movement upwards (z-direction). Since the windowpane is however only fixed after the adjustment process this can becorrected. Thus the window pane body swivels as shown in FIG. 10noticeably about the point A during adjustment.

Through these geometrical features it is possible with suitabledimensions of the radii RI, R2 to place at the spot A at any desiredplace.

The invention is however not restricted to the embodiment of the contactzones 46.1′, 46.1″ and the contact regions 47.1′, 47.1″ as circular arcshaped curved surfaces with the aforesaid design of radii. It is alsopossible to design these as any type of curved or any type of flatsurfaces. However a contact bearing over the entire surface area is thennot reached. The contact zones and/or contact regions shaped in this wayhave a linear contact, with this line wandering as the segments aredisplaced.

A solution of this kind is shown diagrammatically in FIG. 11. Thecontact zones 46.2′, 46.2″ in the position shown in solid lines contactthe contact regions 47.2′, 47.2″ at points P1, P2. The slopes of thetangents T1, T2 at this point are different. The condition has to befulfilled where the tangent T2 with regard to the x-direction has alesser slope than the tangent T1. The orthogonal of the tangents T1, T2meet at the momentary pole MP′

When the displacement part 4.5 moves on the z-axis, the points P1, P2move about the momentary pole MP′. A further position of thedisplaceable part 4.5 is drawn in by dashed lines. It can be seen thatthe slope of the tangents T1′, T2′ alters in the new contact point P1′,P2′. A new momentary pole HP″ is thereby produced. It is clear that themomentary pole MP″ has thereby moved relative to the momentary pole MP′.Thus the designer has the possibility of fixing the movement of themomentary pole MP′, MP″ and thus the displacement path of the windowpane 7 by configuring the path of the contact zones 46.2′, 46.2″ and thecontact regions 47.2′, 47.2″. The shift in the window pane 7 in thez-direction which thereby occurs can be compensated prior to its finalfixing in the ideal position.

The path of movement of the momentary pole shown in FIG. 11 representsthe general case. As a special case the example applies as shown inFIGS. 9 and 10 since the momentary pole MP does not move through theconfiguration illustrated there of the radii R1 and R2.

The displacement of the segments can take place by means such as thosealready described above. These include for example displacement by anadjustment pinion which engages in a spline provided at the side on thedisplaceable part (see FIG. 5). These means are not shown in FIGS. 9 to11.

A further embodiment of the invention is illustrated in FIGS. 12 to 16.Also here the window pane 7 is held between a holding plate 26.5 and adisplaceable part 4.5. An insert 25.5 is provided between the holdingplate 26.5 and the window pane 7. This unit (holding plate 26.5, insert25.5) is tensioned with the base body 1.9. The tensioning is producedthrough a fixing screw 28.6 which runs through corresponding recesses(not shown in further detail in the figures) and is screwed to theholding plate 26.5. The window pane is thereby fixed in the idealposition.

The displaceable part 4.5 consists of two segments 4.5′and 4.5″ whichare connected together through a flexible web 4.5′″. The segments 4.5′and 4.5″ are designed as wedges lying on the x-axis and having differentwedge angles α, β. The position of the segments with the wedge angles α,β can be seen from the sectional diagrams shown in FIGS. 13 and 14. Thetapers of the wedges each point in the same direction. The segments 4.5′and 4.5″ bear with their contact bearing faces 48.1′, 48.1′ against thewindow pane 7. On the opposite side, the segments 4.5′, 4.5″ areprovided with contact surfaces 47.3′, 47.3″ which adjoin contact zones46.3′, 46.3″ of the base body 1.9.

The contact surfaces 47.3′, 47.3″ and the contact zones 46.3′, 46.3″ arehere designed flat. It is however also possible in a similar way to thepreceding example to provide between them a linear or spot contact whosetangents at the contact point between the contact face 47.3′, 47.3″ andthe contact zone 46.3 ′, 46.3″ point in the x-direction and havedifferent slopes.

The method of operation of the carrier described above will be explainedwith reference to FIGS. 15 and 16. The displaceable part 4.5 is hereshown in two different positions. With this illustration to show moreclearly the geometric conditions the holding plate 26.5 including windowpane 7 have not been drawn in.

A displacement on the x-axis results through the different wedge angleα, β, in a differing shift of the contact bearing faces 48.1′, 48.1″ inthe y-direction, whereby the flexible web 4.5″ becomes deformed. Thusthe window pane (not shown here) is turned about an axis lying on thex-axis so that a change in the position of the window pane and an exactcontact bearing against the vehicle body can be achieved.

In order to obtain a bearing of the contact bearing faces 48.1′, 48.1″against the window pane over their entire surface area, the contactfaces 47.3′, 47.3″ and/or contact zones 46.3′, 45.3″ are provided with arestriction which is not shown in the figures.

The displaceable part 4.4, 4.5, 4.6 is reinforced by adjusting means asalready described in the above examples.

In a further design of the invention it is proposed to connect the twosegments together neither rigidly nor flexibly but to arrange themindividually. The segments can then be displaced independently of eachother through adjusting means whereby deliberately preset movementsequences can be produced.

Through this arrangement it is also possible to displace both segmentsin synchronization.
